To all whom a am "Be itflgnown *-that I; Jsmmosi DiGina RETT, a UltlZBIlof the UnitedStates, residingat? Winnsboroj imtfh county of d and ;State,of Texas, have invented certain new] and useful Improvements airng-ne s, of which the followlng 1s a specification? Thls lnventlonrelates to harrows and has:

for its object the provision of a'simple, inex pensive and eflicientimplement by which.

roots of weeds and obno'xious grasses may'be removed from the ground anddestroyed, the

ground being, at the same time, left" in proper conditlon topromotegrowth of desirable plants. One object of the invention is to provldesimple means whereby. the imbe readily relieved of an ac-' cumulationofroots and trash which tends plementv may toclog its operation and defeatits purpose.

The invention is illustrated in the accompanying drawings, in which-Figure 1 1s a plan view of a harrow e rnbodying my improvements; 7

Fig. 2 is a side elevation ofthe same; Fig. 3 is a detail horizontalsection showmg the manner of securingtheharrow teeth. In carrying out myinvention, I employ a substantially triangular frame comprising acentral beam OIdIEtft bar 1 having a clevis animals may bereadilyhitched thereto. To

the rear end of this main'beam or draft bar, I secure a cross beam 3 andforwardly converging beams 4 and 5 extend from the cross beam 3 to thecentral beam or draft bar.

The rear ends of the beams 4 are secured to the cross beam at pointsabout midway between the center of said beam and the ends 7 thereof andthe front ends of the said beams 4=are secured *tothe draft bar by abolt 6 inserted through theinsame andthe-ends of the beam 4, as clearlyshown. Thebeams 5' aresecured at their front ends .to the draft bar '1by a bolt 7 in the same manner and the rearends of these beams 5'arefsecured to the ends of the beam 3, as clearly shown. The 'Iharrowteeth 8 are secured to the beams 4' and 5 by U-bolts 9 fitted around theshanks of the teeth and inserted through the beams 4 and 5, as shown,nuts 10ifitted on the ends 1 ;ofthe U-bolts-and turned'home' against'thebeams l servingv to -clamp the teeth firmly against'the forward sides ofthe beams. The

lower ends A r 'mr'm'asoasmsam, 0s Winn of the harrow teeth are turned,

ifi onir the ground 'andthe'shanks the teeth are se;-arrahged thattheyI' eiztend-slightly 'forward,as well as downwardly from the beams,so thatfth ey will more readily "with- -"*s'tand the strain Placed 19them Upon the draft bar 1, at the'rear end thereof, is a segmental:locking plate 12, which is dis;v

posed concentrically with a rock shaft 13 -journaled in suitablebearings upon said 'rateatednlec. 3, 1 9-18.;

APPIMJt-i i -W 142,022." a

draft bar and upon the beams. A lever 14 is'secured on this rock shaft,at the center of the same,and is equipped with'a latch 15, i -of theusual construction, to engage the holding segment .12 and therebymaintain the lever in any position in which it may be set. Near the endsof the rock shaft 13, I

secure thereto shoes or runners 16 rigidly whichdependfrom the rockshaft and have their lower ends turned rearwardly, as clearly shown.Near the front ends of the beams, I pivotally mount upon the draft bar alever 17 which has its lower end equipped with a shoe or runner 18,similar in all. respects to the shoes or runners 16, and the upper endof this lever 17 is connected by a link 19 with the operating" lever 14.2 attached to 1ts front end so that-the draft in connection with theaccompanying drawlngs. The implement is drawnover the field and theteeth will take into the ground so as to engage under and uprootobnoxious growths. The shoes or runners 16 and 18 may be set so as toclear the ground, as

illustrated ,'n the drawings, or the levers may be adiusted so that thesaid shoes or runners will press lightly upon the surface and therebyprevent the harrow penetrating to such a depth as willunnecessarilyincrease the draft and thereby impose increased strain upon" the draftanimals.

As the roots and I grasses are turned up by the harrowteeth;

.thev. will tend to dragthereon and will ordinarily accumulate in frontof the teethv so that eventually the harrow will be clogged and will notperform the desired work.- In

such event, the operatmg lever 14 is swung rearward and the severalshoes or runners will thereby be caused to impinge against the surfaceof the ground and lift theframe i and the teeth so that the accumulatedtrash 4 i and grass will be discharged in apile'and maybe easilygathered and carried to any place of disposal.

Having thus described the invention, what 5 is claimed as new is? -r Aharrow including substantially triangular shaped inner and outer frames,a draft bar connect ng sald frames,a cley1s' secured to the dra-ftbar ata point spaced V 10 from the apexof the outer frame, verticallyadjustable teeth secured to the outer faces of theconverging sides ofvthe innerand outer frames and; extending for the entire length thereofandeach including a shank 15 substantially,rectangular. in crosssectionand extending downwardly and forwardly from I theadjacentframe, the freeendf of the shank of each tooth being flattened and dis osed atsubstantially right'angles to the -slfank and at an angle to the side ofthe 0 adjacent supporting frame, the terminals Of'the teeth beingpointed and extended in th'e'dirfection of the draft cle is, and: U-

Shaped-fastening devices extending through the COHVQI'glItgfi-ldGS'Ofthe frames and engaging the shanks'of the teeth for clamping said teethin.adjustedrposition. 1
